Tape cartridge

Abstract

A tape cartridge has a housing having upper and lower walls defining an interior therebetween, a pair of tape winding elements provided on left and right sides of the interior of the housing, the tape winding elements being supported for rotation by the upper and lower walls of the housing, a tape wound around the tape winding elements, a restriction sheet provided between the upper wall of the housing and windings of the tape, and a restriction means made of a lower bouncing material. The restriction means is provided in a region on a rear side of a line connecting centers of the tape winding elements and opposing the windings of the tape and also between the upper wall of the housing and the restriction sheet so that, when the restriction sheet is forced toward the upper wall by an edge of laterally moving tape, the restriction means receives the forced restriction sheet and then resiliently returns the restriction sheet toward the tape winding to prevent a misaligned winding of the tape.

1 . A tape cartridge, comprising:
 a housing having upper and lower walls defining an interior therebetween;   a pair of tape winding elements provided on left and right sides of the interior of the housing, the tape winding elements being supported for rotation by the upper and lower walls of the housing;   a tape wound around the tape winding elements;   a restriction sheet provided between the upper wall of the housing and windings of the tape; and   a restriction means made of a lower bouncing material, the restriction means being provided in a region on a rear side of a line connecting centers of the tape winding elements and opposing the windings of the tape and between the upper wall of the housing and the restriction sheet so that, when the restriction sheet is forced toward the upper wall by an edge of laterally moving tape, the restriction means receives the forced restriction sheet and then resiliently returns the restriction sheet toward the tape winding to prevent a misaligned winding of the tape.   
   
   
       2 . The tape cartridge of  claim 1 , wherein the restriction means is secured directly or indirectly to the upper wall of the housing. 
   
   
       3 . The tape cartridge of  claim 1 , wherein the restriction means is made of resilient rubber or plastic material. 
   
   
       4 . The tape cartridge of  claim 2 , wherein the restriction means has an elongate rod-like restriction member made of resilient rubber or plastic material, the restriction member being extended from left to right in the region. 
   
   
       5 . The tape cartridge of  claim 1 , wherein the restriction means has a plurality of restriction members disposed separately in the rear region, each of the restriction members being made of a compressive coil spring. 
   
   
       6 . The tape cartridge of  claim 1 , wherein the restriction means has a plurality of restriction members disposed separately in the rear region, each of the restriction members being formed by folding a portion of the restriction sheet.
